All newly obtained lesser gems of Shadow Rarity and above have either Fierce (Physical Damage) or Arcane (Magic Damage) in their name. That means, their stats will never roll into opposite damage. Old lesser gems without Fierce\Arcane naming can still roll to any sort of damage.

Lesser Cosmic Gems can only be unboxed from Cosmic Gem Boxes, obtain on Geode Surface. For more on Cosmic Gems see Geode Surface Gear.
